"Up the mountain?" The village head looked at Feng Anyan and he Mulan in doubt and asked strangely, "what are you doing up the mountain? You two young people are all insects and beasts on the mountain. What do you do if you are hurt?"

"Village head, after investigation, we found that many people in the village were ill." He Mulan said hastily, "we suspect that it has something to do with the water source. It is very likely that the water source has been polluted."

"No one in our village has money to buy pesticides, where will it pollute the water." The village head still didn't believe it.

"Is this well in your house connected to the lake on the mountain?" Feng Anyan suddenly asked.

"No, the water is from other places. My legs are not good. I always let my wife go out to carry water. It's too tired, so I set up a well by myself." The village head explained solemnly.

"We want to go to the water source on the mountain and have a look." Feng Anyan insisted.

The village head has no way. After all, they are the people sent from above. They insist that they can't stop them. Moreover, they have told them about the possible danger, and they still look like they are going.

At last, the village head sighed and agreed, but because the village head was busy, he couldn't lead the way in person, so he asked them all the way.

"Is it straight along the village? The village head said that if there are people who wash clothes on that side occasionally, they will know the way. " He Mulan asked with a frown.

Feng Anyan shook his head and said: "since the village head asked us to ask while walking, then we..."

Feng Anyan says here, but suddenly there is no voice. He Mulan feels strange and looks up at Feng Anyan. He looks at the front, puzzled.

He Mulan also followed to see to the front, saw a person standing in front of the dirt roadside, looking at unexpectedly a little familiar.

"That's not..." he Mulan's memory is good, immediately remembered that person is the person she and Feng Anyan saw on the way.

Seeing that he seemed to have been discovered, the man came forward and looked at Feng Anyan.

He Mulan saw clearly the man's appearance. He was about thirty years old. Although his skin was a little dark, it was not as rustic as those country men.

"Who are you?" Feng Anyan asks coldly, for fear that he has bad intentions, and protects he Mulan intentionally or unintentionally.

"Don't be nervous. My name is Hu Qingshan. I'm a teacher in Shitou village and town." Hu Qingshan explained with a pleasant face.

"Teacher?" He Mulan was stunned that there were teachers in such a poor village.

"Yes, I came here voluntarily." Hu Qingshan said faintly, then he looked at he Mulan and said, "are you from outside? What are you doing here? "

"Why do you ask so clearly?" Feng Anyan is a little wary.

"Actually, I've been a little confused." Hu Qingshan knew that if he didn't explain clearly, it would be hard to get Feng Anyan's trust, so he readily explained, "I'm here to support teaching. I'm just teaching some primary school students, but my original major is medicine."

After graduation, Hu Qingshan volunteered to teach in Shitou village. Because Shitou village and the small town in front of him are located in a remote place, the land is poor, and there is no source of income, so people here don't pay much attention to knowledge, and there are less than ten children in the small town and village.

Hu Qingshan went to the town to teach for a week, and stone village to teach for a week. This week, he just finished his lesson in stone village and was planning to go back to the town when he saw Feng Anyan's car.

Although Hu Qingshan has been in the countryside for seven or eight years, he occasionally goes to the city, so his knowledge is not backward. He can see at a glance that the car is valuable, so he stands and looks at it for a while.

Over the years, Hu Qingshan has found that the villagers' physique is getting worse and worse. He is a medical major. When he first came here, he smelled the smell of the water in Shitou village and thought it was wrong.

"The water is not clean, but after all, I don't have any professional equipment and can't test it. People here don't pay much attention to it. It's normal to throw some rubbish into the water, but it won't form this kind of taste." Hu Qingshan said seriously, "besides, I also found that some villagers are seriously ill, which is obviously a symptom of cancer."

He Mulan took a look at Feng Anyan. Both of them are serious. It seems that what they want to check is coming to the surface.

"We're going to look around the water source." He Mulan said.

"I've been to the water source, but I haven't found anything." Hu Qingshan sighed. Although the villagers knew that the water quality was bad, there was no running water in the village. They had to drink the water. Although the village head had a small well, the bottom of the well was just a small spring hole, which could not afford to feed the whole village.

"There must be something." Feng Anyan said firmly.Hu Qingshan took a look at Feng Anyan's insistence and said, "I'll take you."

Along the way, they met a lot of villagers, who seemed to like Hu Qingshan very much and were warmly greeting.

"Why did you come here as soon as you graduated?" He Mulan asked, puzzled. Since Hu Qingshan is a medical major, he can find a good job in the city. There is no need to suffer here.

"At first, it was because something happened at home. I came here to relax. But later, I couldn't walk away any more. Every time I said I wanted to leave, the children looked at me eagerly for fear that I would never come back." Hu Qingshan is full of tender feelings.

He Mulan is also a teacher. He deeply understands that the responsibility of resistance, the children's expectations and love are the most unforgettable.

The three soon came to the mountain where the water source was. They saw a group of women chatting and walking up the mountain with clothes in their hands.

"Isn't this Mr. Hu? Didn't you go back to town?" When the women saw Hu Qingshan, they were surprised and asked in their native dialect.

"There's something about coming back." Hu Qingshan replied with a smile.

When other women saw he Mulan and Feng Anyan, they couldn't help talking to each other. Hu Qingshan took he Mulan and Feng Anyan to go up. The mountain road was not steep. Not long after they went up, they saw an oval Lake in the middle of the mountain. Beside the lake, there was a small pool.

Those women carrying clothes, chattering came to the small pool, sat down and began to wash clothes nimbly.

"Women wash their clothes in small pools, and drink water from large lakes." Hu Qingshan explained.

"What about the water in the stream?" He Mulan asked again. She came up to a woman who was washing clothes.

Hu Qingshan and Feng Anyan also followed. Hu Qingshan explained, "the water in the stream is also separated from the lake. Besides the well of the village head's family, this is the only water source."

"The village head's well." The woman who washed the clothes seemed to have finally found a chance to cut in. She said in a hurry, "that well has very little water, regardless of its height."

"Do you usually come here to wash clothes?" He Mulan squatted down and watched curiously as they put their clothes into the pool.

"Well, the stream and lake are so far away from the village, so we come here to wash our clothes because the water we pick up from home is for food." The woman answered.
